The front end of the left-hand 75 struction and organization as hereinafter de wedge arm 19 is bent forwardly as at 21 and scribed and claimed; and in order that it may provided with a screw-seat to receive the be fully understood reference is to be had to threaded end of screw 22, having its nonthe accompanying drawing, in which threaded portion journaled in the opening Figure 1, is a section on the line II of formed by the grooves 14 of blocks 13, longi- Fig. 2.

The screw is turned fit together and are disposed by preference by means of the key 26 or other suitable dowithin the tubular bar and about a quarter vice. It is therefore proof against manipulation by anyone unless provided with a key or equivalent tool and because of the threaded relation between the screw and wedge clamp the latter is locked against accidental movement in either direction.

From the above description it will be apparent that I have produced a loose leaf post binder possessing the features of advantage enumerated as desirable in the statement of the object of the invention and which may be modified in various particulars without departing from the spirit and scope of the appended claims.

Having thus described the invention what I claim as new and desire to secure by Letters Patent, is

1. In a loose leaf binder, a tubular bar, blocks secured in one end and provided with mating grooves, a screw journaled in said blocks and provided with collars at opposite sides of the latter, a slidable clamp comprising a pair of approximately parallel wedge arms converging with and bearing at their front ends against a wall of the tubular bar, one of the wedges having at its rear end a brace arm also bearing against said wall and the other wedge .a front arm provided with a screw seat engaged by said screw.

2. In a loose leaf binder, a tubular bar, blocks secured in one end and provided with mating grooves, a screw journaled in said blocks and provided with collars at opposite sides of the latter, a slidable clamp comprising a pair of approximately parallel wedge arms converging with and bearing at their front ends against a wall of the tubular bar, one of the wedges having at its rear end a brace arm also bearing against said wall and the other a front arm provided with a screw seat engaged by said screw, and guiding means for the slidable clamp intermediate of its wedge arms.

3. In a loose leaf binder, a lower cover member provided with a plurality of up wardly projecting posts, an upper cover member provided with a tubular bar having alined openings in its upper and lower walls to slidingly engage said posts, block-s secured within and near one end of said tubular bar, a screw journaled in said blocks, meansto prevent longitudinal movement of said screw when turned, and a slidable clamp eX- tending longitudinally within the tubular bar and provided with a pair of substantially parallel wedge arms contiguous to said openings and between said posts and the rear wall of the tubular bar, and provided with a screw seat engaging said screw and adapted when the latter is turned in one direction to act as wedges between the back wall of said tubular bar and said posts and when turned in the opposite direction to withdraw from engagement with the latter.

4. In a loose leaf binder, a lower cover member provided with a plurality of upwardly projecting posts, an upper cover member provided with a tubular bar having alined openings in its upper and lower walls to slidingly engage said posts, blocks secured within and near one end of said tubular bar, a screw journaled in said blocks, means to prevent longitudinal movement of said screw when turned, a sliding clamp extending longitudinally within the tubular bar and provided with a pair of substantially parallel wedge arms contiguous to said openings and between said posts and the rear wall of the tubular bar and provided with a screw-seat engaging said screw and adapted when the latter is turned in one direction to act as wedges between the back wall of said tubular bar and said posts and when turned in the opposite direction to withdraw from engagement with the latter, and a key detachably secured upon the screw for turning the same in either of said directions.

5. In a loose leaf binder, a lower member having upwardly projecting posts, an upper member having a bar fitting on said posts to slide up and down thereon, a clamp carried by said bar and consisting of a body portion extending longitudinally of the bar and substantially parallel oblique resilient arms at opposite ends of the body portion and arranged between the posts and a part of the bar, one of said arms terminating in a brace arm also bearing against said part of the bar and the other in an oppositely projecting arm provided with a thread seat extending longitudinally of the bar, and a screw arranged longitudinally of and bearing a swivel relation to the bar and having its threaded portion engaging said thread seat.

In testimony whereof I affiX my signature, in the presence of two witnesses.
